“Doug and I never had an affair,” Keller told FOX411. “I was only trying to be a supportive mother when she told me she wanted to marry Doug, but I didn’t realize the impact a man that age would have on a girl Courtney’s age and [my decision] will haunt me for the rest of my life.”

Stodden and Keller have been estranged since May when Keller stepped down as her daughter’s manager. At the time, Stodden accused her mother of using her to become famous, and Keller claimed it was “too difficult to work with people” that had differing opinions regarding the future of Stodden’s career.

In an attempt to work out their differences, the pair signed on to Lifetime’s “Mother/Daughter Experiment: Celebrity Edition” to work on their relationship. In a clip for the show, Stodden says her mom tried to steal her husband.

“When Doug and Courtney first got married, Doug had a terrible anger problem and Courtney would come to me saying she wanted out,” Keller revealed. “Within three months of marriage she wanted out, and Doug was very upset and came to me.

“Doug and I became emotionally dependent on each other at the time, and he was coming to me asking what he should do … When it was clear that Courtney was leaving he begged me to stay with him and I thought it was unusual … He said he didn’t want to be alone, and he had developed feelings for me … I never wanted Courtney to leave … I tried so hard to keep those two together.”

Keller said this happened in 2011 and she believed the family had moved passed it.

“I just think this is misplaced anger that I stepped down as her manager. I found my own love. I found my own life, and I moved forward. It’s very hard for me to hear her say I was trying to steal her husband from her.”

On the show, Stodden also claims her mom will do anything to be famous.

“Courtney accuses me of wanting fame at all costs. That is simply not true,” Keller said. “If that were true — that I want fame at all costs — I would have accepted the porn offer that Vivid Entertainment put towards me. That would have gotten a lot of publicity, but I was not interested in that. I was more interested in pursuing my management company. I do not know if I will ever understand why she feels that way.”

A rep for Stodden and Hutchison did not immediately return FOX411’s request for comment.
